HookSense: features, pricing and alternatives

About HookSense

HookSense gives you a callback URL, shows incoming webhooks live from providers such as Stripe, GitHub, Shopify, Slack, Twilio and SendGrid, and keeps a searchable history of 14 to 90 days. The site says payloads appear in under 50 milliseconds, are encrypted at rest and are deleted according to your plan's retention.

You can replay a captured request to localhost or staging, edit the body first or repeat it many times to test idempotency, and verify signatures with timing-safe HMAC checks for Stripe, GitHub and Shopify. Provider and event type are detected automatically and URLs are readable. An MCP layer lets agents create a callback endpoint and wait for a verified result instead of polling.

The tool also tracks success rate, volume and latency on the same endpoint in production, and the site compares it with webhook.site and ngrok. Starting needs no signup or credit card, with paid plans extending retention and limits on the pricing page.
